Strathcona was established in 1924 by its founding
principals, Florence Livingstone and Henrietta Hughes, with a small number of pupils, both boys and girls.{{cite web In 1942 the school was purchased by the
Baptist Union for the purpose of establishing a Baptist school for girls, and the school was renamed Strathcona Baptist Girls Grammar School. Miss Featherstone commenced as headmistress in 1943, serving the school for 10 years. Enrolments increased rapidly and despite strict building restrictions after the
Second World War, facilities were expanded providing for up to 200 girls. In November 1969 Strathcona purchased the historical building 'Tay Creggan' and it is now the Year 9 campus, located in
Hawthorn on the banks of the
Yarra River. Built in 1893 in the
Queen Anne style as a family home, it became an important and fashionable part of Hawthorn social life. It was designed by architect
Guyon Purchas for his own use. He was later forced to declare
bankruptcy and sell the house. ==Principals==
